Patent JP-S5588444-A (JP)
Title: Optical communication system
Inventor: KUROSAWA NOBORU
IPC: H04B10/61
Filed: 1978-12-26
Abstract: PURPOSE:To ensure the transmission for the high-quality signals with the low loss by piling the carrier signal with the amplitude modulation received onto the original modulation signal equivalent to the detection signal of the carrier signal and then securing nearly the constant value for one side of the envelope line of the carrier signal for application to the electricity-light conversion element. CONSTITUTION:The carrier signal with the amplitude modulation received is produced along with the original modulation wave signal featuring the same amplitude as the carrier signal, and these signals are piled onto the original carrier signal to obtain the 2nd carrier signal. And in case the light emitting diode is driven, the coincidence is secured between the lower limit of the operating range of the diode and the side where the envelope curve of the driving current becomes constant. Thus the power consumption is reduced for the same optical force, and at the same time the mean reception power is reduced in case the high-sensitivity element is used as the photodetector. As a result, the S/N ratio can be enhanced.

Title: Semiconductor memory device
Inventor: KOSUGI RYUICHI
IPC: G11C11/407
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory device which can adjust an access time when a delay signal becomes the level to instruct an output due to the function of a delay circuit which instructs an output with a delay time corresponding to the level of a delay control signal. SOLUTION: When a delay control signal DC is in the high level, a read/write signal RW is set to the high level to instruct the read operation and thereby a read data RD is read from a memory cell in the SRAM1000. When an output enable signal OE changes to a low level to instruct data output, an output signal OEB of the OE buffer 130 is set to the high level. A delay circuit 180 for receiving this OEB can change a delay time with a delay control signal DC and therefore the access time until an output data DQ is output is short. Therefore, if data collides when the output data DQ is output to a data bus to be used in common by a plurality of SRAM1000, such collision of data can be avoided by setting the delay control signal DC to the low level.

Title: Information processor
Inventor: KITO AKIRA
IPC: G06F12/00
Filed: 1986-07-11
Abstract: PURPOSE:To effectively utilize a large-capacity register suitable for an object to be processed, by matching the interface of an internal register file selecting signal line to the interface of a memory selecting signal line. CONSTITUTION:When an external interruption signal 13 is inputted to an infor mation processor 31, an up-down counter 14 is counted-up by '1' and a register file address 2 is increased by '1'. Since the interruption input 13 is inputted to the interruption input 14 of the processor 31 through a timing circuit when the signal 13 is inputted, the register file which is selected before the interrup tion input is inputted changes to a new register file together with the interrup tion input when it is viewed from the processor 31 side and the process is contin ued. Moreover, when a memory address 5 which is determined by a decoder 41 is accessed by the processor 31, a signal is inputted to the countdown input of the counter 14 and the address 2 is decreased by '1', and then the register file before the interruption signal is inputted is again selected. Therefore, the saving and restoration of a register can be made equal to those realized by accessing the memory address.

Abstract: PURPOSE: To reduce the insulation distance between a high-voltage coil and a low- voltage coil by embedding a coil comprising a hollow conductor in resin having excellent heat conductivity, and by circulating cooling medium in the coil.  
     CONSTITUTION: A coil 23, wherein a low-voltage coil 20 and a high-voltage coil 21 are put in resin 22 to form one body, is arranged around the outside of a core 1. The coil 20 is formed in a hollow tubular coil which is wound in spiral shape. The biginning portion and the end portion of the coil are connected with the end of a electro-conductive lead pipe 30. When a load current flows, the temperature of the coils 20 and 21 increases. When the temperature of the coil 20 reaches the evaporating temperature of the cooling medium in the coil 20, the cooling medium is vaporized by absorbing heat of vaporization from the coil 20, and is sent to a cooler 26, The vaporized cooling medium is returned to liquid and guided to the coil 20 again. Heat generated in the coil 21 is transmitted to the coil 20 through the resin 22 and cooled. In this constitution, the insulation distance between high and low voltage coils can be reduced.
